Sewage Treatment Plant - Submerged Aerobic Fixed Film (SAFF)

Submerged Aerated Fixed Films (SAFF) technology is a process used to reduce the organic loading of residential and commercial sewage / waste water, and in doing so will reduce the Biological Oxygen Demand (BOD) and a significant quantity of Suspended Solids (SS) which if otherwise untreated would contaminate river and sea outfalls, in other words it is used to substantially improve effluent discharge quality. As with traditional sewage treatment, Submerged Aerated Fixed Films technology uses three stages of dealing with commercial and residential sewage / waste water:



Primary Settlement

Where larger solids settle into the bottom of the primary tank and are removed periodically as sludge, and where other buoyant materials float upwards to be removed usually by a scraping/screening method.


Secondary Treatment

Where larger solids settle into the bottom of the primary tank and are removed periodically as sludge, and where other buoyant materials float upwards to be removed usually by a scraping/screening method.


Final Settlement / Clarification

The usual design criteria is to produce an effluent quality typically better than BOD 30 mg/l & SS better than 100 mg/l. Without additional nitrification and treating, normal domestic sewage ammonia discharges are around 10 mg/l.

DISCHARGE QUALITY

The usual design criteria is to produce an effluent quality typically better than BOD 30 mg/l & SS better than 100 mg/l. Without additional nitrification and treating, normal domestic sewage ammonia discharges are around 10 mg/l.
